Polyurethanes based on polyether blends |
摘要 |
Polyurethane compositions based on aliphatic diisocyanates, or prepolymers of aliphatic diisocyanates, and blends of ethylene oxide capped polypropylene glycol polyethers of at least tri-functionality with ethylene oxide capped polypropylene glycol polyethers of di-functionality are disclosed. Suitable aliphatic diisocyanates comprise tertiary aralkyl isocyanates with a preferred isocyanate being para-tetramethylxylene diisocyanate (p-TMXDI). The compositions disclosed include reaction injection molding compositions.
